Emulator

What's the problem? Describe what went wrong.

Dolphin hangs for a good 15-20 seconds if the language is not the system default; in my case, Portuguese (Brazil). I prefer to set the interface to English, because the most help I can get when searching for game configs, or even ini edits, are in English. Not that the Brazilian Portuguese Dolphin community is bad, but information in English is vaster.

After that time the game list shows up normally.

What steps will reproduce the problem?

1-Start a fresh Dolphin setup
2-Change interface language to anything but the system default
3-Restart Dolphin

Which versions of Dolphin did you test on? Does using an older version of Dolphin solve your issue? If yes, which versions of Dolphin used to work?

It's been a while since I got to play in Dolphin, so I downloaded the latest build (5.0-383 as of time of writing), but I tracked that this bug started on 5.0-211 (Externals: Update wxWidgets to 3.1.0, as the build description). On 5.0-206 (5.0-209 has no download link for me) it doesn't happen.

What are your PC specifications? (CPU, GPU, Operating System, more)

Windows 8.1 Pro 64 bit
AMD Athlon II x2 240 2.8Ghz
5GB RAM
NVIDIA GeForce 9600GT 1GB

Is there any other relevant information? (e.g. logs, screenshots,
configuration files)

I don't have other languages installed right now to test if that language won't hang on Dolphin, but I could try downloading if deemed necessary.
